It is also known, dai3 the armature of a relay, not only indirectly actuates a contact arrangement, but that he himself works as a switching element of at least one I-Iutzstromkreis.

In known embodiments of electromagnetic relays, the armature has a mechanical armature bearing, which is formed, for example, by a bearing pin or by a bearing spring designed accordingly. However, every mechanical bearing of an armature causes bearing friction that cannot be neglected in many cases and which is of considerable importance, particularly in relays with a high response sensitivity.

In the case of a polarized miniature circuit of the type described in detail at the beginning, the described "laugh parts" are eliminated by the fact that the 7-shaped rotating armature with its two ends is arranged in pairs between the two ends

This results in one automated production particularly simple work processes.

An advantageous embodiment of the invention provides. that for the premagnetization a permanent magnet of the same polarity is inserted between the contact elements arranged in pairs in a form-fitting manner. In addition, the wedge-shaped course of the contacts, which are arranged in pairs, becomes a part of the V-shaped shape of the rotating armature in the sense of an electricity-wise favorable.

To control the polarized relay according to the invention, an axially 'acting excitation field is expediently used, this field being reversible by reversing the polarity of the excitation in such a way that the armature von.dor. switches from one rest position to the other.

Since the partial demagnetization can also be carried out in the final state of the relay, then a achieve uniform production of such relay systems, if the manufactured relays are to work with different operating data.
